a wave that interferes

For “A Wave That Interferes” (2011—Present) two transparencies with simple black and white patterns are moved by hand to create visual interference – a moire effect – that is translated into sound as the changing shape of a waveform. As the visual pattern becomes more complex (diamond patterns emerge), harmonics are added, and the soundwave becomes a square. As the visual pattern becomes simpler (separates into lines), harmonics are subtracted, and the soundwave becomes a triangle.
